Flow cytometric analysis of ploidy levels in two seed-infesting Megastigmus species: applications to sex ratio and species determination at the larval stage.
The article focuses on the flow cytometric analysis of ploidy levels applied to sex ration and species determination at the larval stage. Biological invasions have been widely associated with severe changes in both ecological and economic components of ecosystems. Increasing worldwide exchange of tree materials is a critical factor favouring biological invasions through considerable extensions of the distribution range of forest insects.
